Transaction sign issue on Ledger Nano X

[191855]

Describe the bug (Please enter details, the more detail the better)
Ledger Nano x is connected to the wallet but when I try to initiate a transaction, It is just stuck at "Connected, waiting for confirmation on device" and I see no pop-up on my ledger. And I see below error from debug logs,

[2023-02-04 14:01:12.836] [warn] API Controller: channel handling error: Error: cannot open device with path \?\hid#vid_2c97&pid_0004&mi_00#a&277ff074&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030} Error: cannot open device with path \?\hid#vid_2c97&pid_0004&mi_00#a&277ff074&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}

Hi @191855

Is the version of Ledger CKB App v0.5.5?

We've found an Inconsistent address issue(Magickbase/neuron-public-issues#98 (comment)) on connecting to Ledger X & Ledger CKB App v0.5.5. And during the debugging, we found Ledger Nano X & Ledger CKB App v0.5.5 hung on signing a message.

Please degrade to v0.5.0, which works well with Neuron.

Yes on version v0.5.5 on my ledger. How do I degrade to v0.5.0?

Our tester was trying to degrade it, too. I'll add the solution here if he succeeds. But it's the weekend there, so the reply would be 2 days later.

Or you can open a ticket in Ledger Support(https://support.ledger.com/hc/en-us/categories/4404369571601-Support?support=true), they should be more professional about it.

Thanks for the link. Do you think downgrading the neuron app to a particular version would help in any way?

[191855]

And also link you shared is related to Ledger live app. I'm not sure if downgrading the ledger live app itself downgrades CKB app to v0.5.0. Are you sure?

To debug the inconsistent address issue mentioned above, we used Ledger Nano X & Ledger CKB App v0.5.0 to connect Neuron, it succeeded; then we upgraded it to Ledger App v0.5.5 and went through the same steps, it failed.

Since our tester hasn't downgraded it to v0.5.0 for double-checking, I cannot say it will be 100% successful. I'll attach the result of downgrading here once he tests it.

[Keith-CY]

And also link you shared is related to Ledger live app. I'm not sure if downgrading the ledger live app itself downgrades CKB app to v0.5.0. Are you sure?

I cannot say that, it's the first time we have to do it. But I'll share the solution of downgrading here once our tester succeeds.

[191855]

Any idea from what version CKB started supporting ledger? I tried downgrading to multiple versions and had no luck with CKB app. Still shows v0.5.5 available to install on Ledger live app. Now I downgraded all the way to "Ledger Live 2.30.0" and I see CKB doesn't support this level.

[191855]

FYI - Downgrading the ledger live to any older version did not help. Pretty much tried 5 - 6 older versions.

[191855]

Curious to know if there is a workaround for this. I just need to transfer my ckb ASAP. Are there any apps that support the ledger ckb hardware wallet?

I know that ckb-cli(https://github.com/nervosnetwork/ckb-cli) is supported by ledger, so you can export the transaction(Export tx in the screenshot) to disk and sign it with ckb-cli & ledger, @TheWaWaR is the developer of ckb-cli and could help

---

PS: the signing fails because of Ledger CKB [email protected]'s bug, so it's possible that ckb-cli cannot connect to ledger too.

Did you hear back anything yet? I guess ckb-plugin-ledger is not up to date or something. "cargo build" itself is failing.

@191855 As for the demotion solution of Ledger CKB App, I have submitted the order to Ledger. We know they're dealing with it, but we haven't received a solution yet. We will get back to you as soon as we receive the feedback.

We got how to install Ledger CKB [email protected] manually, but we didn't run it successfully. Still be connecting to the ledger team, and any new update will be synced here.

Is it safe to try manually installing the app and doing a transaction?

[Keith-CY]

Is it safe to try manually installing the app and doing a transaction?

It should be safe because it's the source code released by ledger, and they provided a guide on how to install it manually. Besides, our partner team had installed it manually to degrade ledger ckb app.

Before this, I would suggest setting 2 configurations that our partner team found useful to re-enable their ledger with [email protected]. Maybe not be your case, but these 2 configurations are required to sign a message/transaction.

1. set configuration => allow sign hash to on
2. set address for to mainnet

We're still waiting for a response from ledger team about this case, any update will be synced here

Hi @191855
Sorry that we haven't figured it out, and we are also blocked by other issues with Ledger + [email protected](listed in Magickbase/neuron-public-issues#103)

This one was reported to the ledger team on 02/09 but no feedback yet.

So, the fix needs to come from the ledger team itself but not from neuron app devs?

I think yes, we're also seeking support from ledger team. [email protected] works well with Ledger Nano S, Ledger Nano S Plus, and Ledger Nano X & Ledger CKB [email protected], so the logic inside Neuron should work.

Besides, the error message in this case shows

cannot open device with path \?\hid#vid_2c97&pid_0004&mi_00#a&277ff074&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030} Error: cannot open device with path \?\hid#vid_2c97&pid_0004&mi_00#a&277ff074&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030}

The question mark in the path is suspicious, but it's from Ledger hardware. This is the question we're consulting with ledger team. Because we've tested our devices and found no one has a descriptor/path in a similar format.

Any idea why I'm facing this error? This is when I'm trying to install Nervos version 0.5.0.

After reading the source code, I've found that prime256r1 was renamed to secp256k1 1.5 years ago, which made the installation broken.

The exception was thrown at https://github.com/LedgerHQ/blue-loader-python/blob/master/ledgerblue/loadApp.py#L132, it blamed that prime267r1 was not a recognizable curve.

Ref:
rename prime256r1 to secp256k1: LedgerHQ/blue-loader-python@6c39a89

---

We can recover the installation by adding

			elif curve == 'prime267r1':
				curveMask |= 0x02

below https://github.com/LedgerHQ/blue-loader-python/blob/master/ledgerblue/loadApp.py#L126

But it would be better to request help from the ledger team.

No luck so far. I kinda give up and also I'm occupied to even think about it. This is so annoying as Ledger taking its own sweet time to address this issue. More than a month so far. I even sent out an email about it.

I have updated the ledger live app to 0.5.6 and no luck. Ledger live has also been updated and downgraded on both m1 and intel based Mac with no luck. Any update on this issue?

Please check if configuration => allow sign hash is on, it will be reset after upgrade

[CountDooku415]

It worked after closing, reopening, disconnecting, a bunch of times. And leaving it pending for minutes. It finally prompted the approve screen. Unfortunately, I was not able to add to Nervos DAO via ledger nano x and neuron. I had to transfer to CK Bull wallet.
